The Diet Zone: A Dangerous Place

    Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically.

    Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale(秤)instead. All we have to do is to swallow or recognize the word “diet” in food labels.

    On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don't have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.

    The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients. Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemicals that go into diet products are potentially dangerous.

    Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological and physical harm that comes from using them.

    It has long been thought that elephants rely on their large ears and bathing in rivers to stay cool in hot climates. New research, however, has showed that the world's largest land animals have a secret trick of controlling their body temperatures.

    Scientists have long been puzzled by temperature regulation(调节)in elephants. Generally, animals with large bodies tend to hold more heat because, compared to their size, they have a small surface area for heat to escape from. Elephants, with their heavy­weight frames, would appear to be at a disadvantage in the heat of their African and Asian habitats, especially because they have thick fur to protect them from bushes and trees.

    Scientists thought that these creatures, which weigh up to 13 tons when fully­grown, grow large ears to help them stay cool. The skin on the ears is thinner, so blood which flows into them cools down more easily. But findings by researchers at two universities in Vienna have showed that elephants are also able to cool down by increasing the blood flow to skin patches(斑) in other parts of their bodies.

    The researchers studied six African elephants at Vienna Zoo as they moved between outdoor and indoor environments to see how the temperature on their skin surface would change. They found up to 15 “hot spots” all over an elephant's body surface, in addition to large patches on the ears. The study shows how these patches expand as the air temperature increases and more blood flows nearer to the skin surface. Other experiments show that elephants in the wild use the same “windows” to control their body temperature.

    Elephants have two additional ways to stay cool: flapping(拍打)the ears and bathing. Together with these tricks, the skin hot spots allow the animals to keep their body temperature always at about 36 degrees—one degree less than humans'.

    Some international languages are widely used for many purposes. Some minority languages will die out and some nations tend to keep minority languages. I reckon that most common used international languages ease our life quality and communication with different nationalities. On the other hand, we need to help improve minority languages.

    There are many languages in the entire world but two or three minority languages die out each year. Some countries try to save dying languages. For instance, Australian Government created a project to save the language and culture of Maori who are Australian aborigines. And there are other projects to keep minority languages such as American Indian language.

    However, the worldwide job market usually requires candidates who can speak English or other international languages. People who cannot speak lingua franca (共通语) could hardly be promoted at work. For example, some companies need an employee who can deal with foreign companies. So most people tend to learn at least one international language that helps them to find a better job.

    Therefore, world needs one common lingua franca that should be spoken in any country. Consequently, one common language should be a required subject in every school. So anyone speaking one common language can travel without worries to any point of the world and trade their products. People will not be forced to learn many languages.

    In conclusion, we should help minority nations to keep their languages for the cultural diversity. To ease the worldwide communication among nations, we should create a common language and provide courses of it. As a result, no one will face a language issue.

    India has a very vast history and heritage (遗产). The country has witnessed some of the most important events in the past and every event has an effect of its own on the culture, religion, lifestyle, and economy of the country. This is one of the leading reasons why tourists prefer India to travel and explore. Historical tours in India provide everything that a traveler expects from his/her journey. These historical tours give an opportunity to study and explore Indian history.

    Historical tours of India generally consisted of four phases: ancient, medieval (中世纪的), modern India and contemporary (当代的) India. Some of the historical travel packages are:

    Forts and Palaces

    The rich cultural past of India is reflected in the countless forts (堡垒) and palaces across the country. Most of the forts were constructed as a defense device to keep the enemy away and palaces were made on the names of the kings and queens. Some of the famous forts and palaces are: Agra Fort (Agra), Fatehpur Sikri (Agra), Hawa Mahal (Jaipur), Amber Fort (Jaipur), City Palace (Jaipur), Gwalior Fort (Gwalior), Mysore Palace (Mysore), Red Fort (Delhi), etc.

    India Heritage Tours

    The main purpose of India Heritage tours is to make Indians as well as tourists familiar with the rich Indian legacy (遗产). The heritage of the country is at least 5000 years. Some of the heritage tours are: medieval heritage, Rajput heritage, Golden Triangle, splendid Gujarat, etc.

    South India Historical Tours

    The Southern India is known for its diversity and there are many places, which (景区) in South India include Goa, Cochin, Kerala, Munnar, Periyar, Kottayam and the list goes on and on.

    Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food, get enough sleep, and exercise regularly.

    Proper nutrition (营养) is important for good health. Your body cannot work well unless it receives the proper kind of "fuel"(燃料).Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白质) ,like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins (维他命) and minerals. However, don't overeat. It is not helpful to be overweight.

    Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little amount of sleep may even result in a change of personality (人的个性). Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.

    Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (寿命). Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.

    If everybody, were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.

The rejuvenating effects of a restorative nocturnal repose are widely recognized; it can engender a state of enhanced well-being. Academics in the field posit that the excellence of one's slumber may indeed be instrumental in the prolongation of one's lifespan.

Male subjects who enjoy a state of somnolent tranquility could potentially extend their existence by a span of nearly five decades in comparison to those bereft of such repose. The female counterparts stand to gain an increment of two decades. Additionally, it has been observed that youthful individuals who adhere to salutary somniferous routines are less susceptible to a premature demise. However, the mere quantity of repose is insufficient to reap the potential healthful dividends; the caliber of one's slumber is equally pivotal.

The parameters of commendable slumber were delineated by a quintet of distinct criteria. These encompassed an optimal duration of seven to eight hours of repose per nocturnal cycle; experiencing difficulty in the initiation of sleep no more than twice per hebdomadal period; similar challenges in maintaining somnolence no more than twice weekly; abstaining from the consumption of any soporific pharmaceuticals; and awakening with a sensation of invigoration on no fewer than five days per septenary cycle.

The conclusions derived from the study intimate that approximately 8% of fatalities, irrespective of their etiology, could be imputed to inadequate somniferous patterns. Dr. Frank Qian, a resident physician specializing in internal medicine at the Beth Israel Deaconess Medical Center in Boston, America, remarked, "A distinct proportional response relationship was discerned. Consequently, an increase in the beneficial elements pertaining to the quality of sleep correlates with a progressive diminution in mortality from all causes."

The research collated data from a populace of 172,321 individuals with an average age of 50, of which 54% were female. These participants were engaged in the National Health Interview Survey, spanning the years 2013 to 2018, which sought to scrutinize the well-being of the American populace, inclusive of inquiries into their somniferous habits.

The subjects were tracked for a mean period of 4.3 years, during which 8,681 succumbed to death. Of these fatalities, 2,610 (30%) were attributable to cardiovascular afflictions, 2,052 (24%) to oncological disorders, and 4,019 (46%) to a miscellany of other causes. Among the male and female participants who reported adherence to all five indices of quality sleep (an optimal quintile score), the expectancy of life was augmented by 4.7 years for males and by 2.4% for females, in contradistinction to those who possessed none or a solitary factor.

Further scholarly endeavor is warranted to elucidate the raison d'être for the dichotomy in the enhancement of life expectancy, with males exhibiting twice the increment observed in females despite equivalent somniferous quality.

A caveat of the study lies in the reliance on self-reported somniferous habits, which were not subjected to objective quantification or verification.
